Pinkie and her sisters have a swimsuit party, but an unexpected question from Trixie has them quite perturbed. She asked them if any of Pinkie's sisters were ticklish, since she already knows Pinkie is. Pinkis might have outfits that show off her belly, but she tends to avoid people like Trixie. Pinkie Pie didn't know this, but Pinkis was dreadfully ticklish, but she doesn't like to be tickled. Pinkis, Limestone, Marble and Pinkamena are open to tickle attacks on their bellies and Pinkie and Obsidian on their underarms, feet and inner thighs. Maud isn't really ticklish so she has nothing to worry about.
